The two women visited Pakistan recently and were forced to remove their mangalsutra, bindi, bangles and footwear by the Pakistani authorities before they were allowed to meet Jadhav through a glass screen.
Delhi BJP spokesperson Tajinder Pal Singh Bagga bought the footwear online and gave the address of the Pakistan High Commission for its delivery.
He also launched an online campaign requesting the "nationalists" to send slippers to Pakistan.
"Over a hundred people sent footwear to Pakistan High Commission within a few hours after I did it," he claimed.
